Nissan has produced some very interesting concept cars in recent years – the Denki Cube, Pivo, Mixim and Pivo 2 just to name a few. Shown in Paris for the first time last weekend, the NuVu is a compact electric car specifically designed to make traveling comfortable in a gridlocked city. The idea is one of a moving urban oasis, with its own tree inside which provides shade for the interior, and generates solar energy via its ‘leaves.’ By-wire steering, unique 2+1 seating, a fast-charging Li-Ion battery system and a rear-mounted electric motor delivering a range of 125 kms and top speed of 120 km/h are among the key features of the Concept which, while not destined for production in its current form, is intended to showcase how a Nissan EV might look and what technology it might contain beyond 2010 when the company begins rolling-out electric cars in Japan and the US.
